Committee Recommendations (2)

The Surrey Heratlands APC agreed that:

  • Metformin MR should be first line on initiation (in line with NICE NG28 Type 2 diabetes Guideline ) to reduce potential gastrointestinal disturbances causing non-adherence with metformin immediate release.
  • For patients already on IR metformin, continue if effective. Switch to MR metformin if IR metformin not tolerated or this is the patient’s preference

Metformin should be considered as the drug of first choice particularly in overweight patients, when dietary management and exercise alone does not result in adequate glycaemic control. Appropriate dose titration and patient education will reduce the likelihood of metformin intolerance - see dose titration guide.
